In-line Polarizer
Description
The In-line Polarizer is designed to pass the light with the specified polarization,blocking the others.the function is tranform non-polarized light into linearly polarized light, for the high extincton ratio.It is also used to enhance the extinction ratio of the signals of precision measurement system, fiber sensor, high speed test instrumentations where the high extinction ratio prosper is required.
